It was anticipated that MISO would start calculating solar capacity credit using the Effective Load Carrying Capability (ELCC) calculation, since MISO got FERC approval for solar as a Dispatchable Intermittent Resource (DIR). But, since MISO only has 4,000 MW of solar forecasted not the 8,000 MW threshold that would trigger the ELCC calculation - MISO kept the solar capacity credit at 50%. Which is good news for the solar industry.

That MISO 50% capacity credit for 2021/22 planning year plus the solar Investment Tax Credit (ITC) extension at 26% for two more years - are both good news for the solar industry. Also good news for the energy storage industry since storage at the same point of interconnection as solar, would increase the capacity value of solar.

Sounds like there are some solar ITCs included in the just passed COVID bill too-- will that change any of the conclusions in this report?

Matt - Not in this report for this year, but possibly in future report a year from now. With more solar registered at MISO, MISO starts calculating solar capacity credit.
